Soloing?
The Tekur race was Michael's perfect Target. Their population was high, and they didn't consider the Interdimensional Flag War with the Tritan Alliance important.
The Tekur deployed to the pocket dimension were ordinary Soldiers and many Elite Soldiers. They were Lords with millions of Summons, but that was not enough to transform their weak Soultraits into supreme abilities. Of course, the Tekur were physically stronger than ordinary humans, and it was unusually hard to kill them because they had Soul Techniques, but Michael was not worried about that.
He had his Soul Techniques and was stronger than any Elite Tekur. After all, only Lesser Lifeforms could enter the pocket dimension when the Flag War started.
Michael hoped that more Elite Tekur would be deployed to this year's Interdimensional Flag War because more Tekur than usual died last year. He guessed the Tekur would deploy a hundred Elite Tekur to the pocket dimension. That would be perfect.
